TECHNOLOGICAL FIELD

This invention is directed to non-dairy almond based formulae for the preparation of infant or toddler formula or other types of supplemental or functional food.

BACKGROUND

Infant formula is a manufactured food designed and marketed for feeding babies and infants under 12 months of age, usually prepared for bottle-feeding or cup-feeding from powder (mixed with water) or liquid (with or without additional water). The U.S. Federal Food, Drug, and Cosmetic Act (FFDCA) defines infant formula as “a food which purports to be or is represented for special dietary use solely as a food for infants by reason of its simulation of human milk or its suitability as a complete or partial substitute for human milk”.

The composition of infant formula is designed to be roughly based on a human mother's milk at approximately one to three months postpartum, although there are significant differences in the nutrient content of these products. The most commonly used infant formulas contain purified cow's milk whey and casein and/or skimmed milk powder as a protein source, a blend of vegetable oils as a fat source, lactose as a carbohydrate source, a vitamin-mineral mix, and other ingredients depending on the manufacturer.

A 2001 World Health Organization (WHO) report found that infant formula prepared in accordance with applicable Codex Alimentarius standards was a safe complementary food and a suitable breast milk substitute.

As most of the infant formulas are based on cow's milk whey and casein as a protein source, many babies develop allergy or intolerance condition that may be at times, life threatening.

Cow's milk allergy is a food allergy, an adverse immune reaction to one or more of the constituents of Cow's milk (most commonly the protein alpha S1-casein). This milk-induced allergic reaction can involve anaphylaxis, a potentially life-threatening condition.

The principal symptoms are gastrointestinal, dermatological and respiratory. These can translate to: skin rash, hives, vomiting, and gastric distress such as diarrhea, constipation, stomach pain or flatulence. The clinical spectrum extends to diverse disorders: anaphylactic reactions, atopic dermatitis, wheeze, infantile colic, gastroesophageal reflux (GER), oesophagitis, allergic colitis, headache, oral irritation, and constipation. The symptoms may occur within a few minutes after exposure in immediate reactions, or after hours (and in some cases after several days) in delayed reactions.

Some babies may develop or are born with lactose intolerance which is a non-allergic food sensitivity, and comes from a lack of production of the enzyme lactase, required to digest the predominant sugar in milk. Adverse effects of lactose intolerance generally occur after much higher levels of milk consumption than do adverse effects of milk allergy. Milk protein intolerance (MPI) is delayed reaction to a food protein that is normally harmless to the non-allergic, non-intolerant individual. Milk protein intolerance produces a non-IgE antibody and is not detected by allergy blood tests. Milk protein intolerance produces a range of symptoms very similar to milk allergy symptoms, but can also include blood and/or mucus in the stool. Treatment for milk protein intolerance is the same as for milk allergy. Milk protein intolerance is also referred to as milk soy protein intolerance (MSPI).

For formula fed infants, milk substitute formulas are used to provide a complete source of nutrition. Milk substitutes include soy based formulas; hypoallergenic formulas based on partially or extensively hydrolyzed protein, and free amino acid-based formulas.

Non-milk derived amino acid-based formulas, known as amino acid formulas or elemental formulas, are considered the gold standard in the treatment of cows milk allergy when the mother is unable to breastfeed.

Hydrolyzed formulas come in partially hydrolyzed and extensively hydrolyzed varieties. Partially hydrolyzed formulas (PHFs) are characterized by a larger proportion of long chain peptides and are considered more palatable. However, they are intended for milder cases and are not considered suitable for treatment of moderate to severe milk allergy or intolerance. Extensively hydrolyzed formulas (EHFs) are composed of proteins that have been largely broken down into free amino acids and short peptides. Casein and whey are the most commonly used sources of protein in hydrolyzed formulas because of their high nutritional quality and their amino acid composition.

Soy based formula may or may not pose a risk of allergic sensitivity, as some infants who are allergic to milk may also be allergic to soy. Also soy based formulas are not recommended for infants under 6 months.

Infant formulas also come in a variety of types:

Cow's milk formula is the most commonly used type (e.g.: Similac, Enfamil).

Soy protein based formulas are frequently used for infants allergic to cow's milk (e.g.: Isomil, ProSobee).

Partially hydrolyzed formulas (e.g.: Good Start and Gentlease brands) are marketed as having improved digestibility.

Extensively hydrolyzed formulas (e.g.: Alimentum, Nutramigen, and Pregestimil) are considered “hypoallergenic”. One study reported that 90% of children with cow's milk allergies will tolerate them.

Amino acid based formulas (e.g.: Neocate, EleCare, and Nutramigen AA) are more expensive, but are reported least likely to cause allergic reactions.

Hypoallergenic formulas, such as those containing free individual amino acids, and sometimes referred to as elemental infant formula, are considered to reduce the likelihood of certain medical complications in babies with specific health problems, such as severe allergies to cow's milk and soy. Made of purely synthetic monomeric amino acids, they are often considered quite foul-tasting, and it is not uncommon for infants to reject elemental formulas after having been established on a sweeter-tasting regular formula, thus the level of compliance of infants in an age wherein feeding is crucial, such incompliance is life threatening.

SPIFs (Soy Protein Infant Formulae) contain phytoestrogens, mostly isoflavonoids (particularly diadzein, genistein). It was shown that these substances tend to bind to estrogen receptors and behave as pro- or anti-estrogens. The amount of phytoestrogens in SPIF (32-47 mg/liter) is 40 times higher than the amount in breast milk. Consumption of isoflavonoids from SPIF reaches 11 mg/kg body weight per day, and their levels in infant blood were 13,000 to 22,000 times higher than the blood levels of estrogen-like substances in the first years of life. Infants who are fed only on SPIF are exposed to a daily consumption of isoflavonoids that is 4-13 times the amount presumed to have a physiological effect on balancing the menstrual cycle in women. Recently the scientific literature has raised some concerns regarding the vast consumption of SPIFs regarding the fact that phytoestrogens could have an adverse effect on infant and child growth (they are not recommended for premature infants weighing less than 1800 grams), development and puberty, bone health and thyroid function. In addition, the fact that most of the soy crops are genetically engineered the use of SPIF is not recommended in certain countries and is regulated to the extent of requiring a prescription for administration for infants having severe allergies.

There is therefore a true need in the art for a non-dairy formula for infants that can provide all essential nutritional needs similar to the gold standard of breast milk nutritional profile without the disadvantages of currently known non-dairy formula.
